Network Participation and Credentialing

Thank you for your interest in becoming a participating provider at AmeriHealth New Jersey.

Professional Providers

Professional providers include but is not limited to the following specialties: physicians, radiologists, CRNP, physical therapists, registered dieticians, etc.

Most licensed practitioners are board-certified physicians. If a physician is not board certified, the required number of educational years deemed sufficient per the Accreditation Council for Graduate Medical Education (ACGME) guidelines would need to be primarily source verified. There are some instances where a practitioner is not board certified, and the educational institution per their policy requires a payment for the verification of a completed program. As needed for cases where education requires a charge, AmeriHealth New Jersey will place the responsibility on the practitioner for the required verification from the institution to be sent directly to the Credentialing Operations processor.

All providers interested in participating must complete the Practitioner Participation Form.*

Important credentialing notes

  • Any professional provider interested in participating in our network must complete the Practitioner Participation Form.
  • Any credentialing application request not received through the Practitioner Participation Form will be returned with instructions to submit the request using the form.
  • The Practitioner Participation Form is only for credentialing applications.
  • Certified registered nurse practitioners (CRNP) must have a collaborative agreement with a participating physician who holds a current and unrestricted license. The training and scope of practice of the collaborating physician must be consistent with the practice of the CRNP. To see scenarios where CRNPs are only allowed to be contracted and credentialed with AmeriHealth New Jersey, please read this article.

Note: Behavioral Health Providers

AmeriHealth New Jersey currently works with Magellan Healthcare, Inc. (Magellan) to provide a behavioral health network to its members. Effective January 1, 2023, we are insourcing the network and are directly contracting with behavioral health providers.

If you have not yet signed an AmeriHealth New Jersey Professional Provider Agreement but are currently participating with Magellan, you will be considered in-network for our members and will continue to be reimbursed according to Magellan’s reimbursement terms. If you would like to receive an enhanced reimbursement under the terms of the AmeriHealth New Jersey agreement, please follow the process outlined below.

If you are a behavioral health provider interested in joining our network:

  • If you do NOT currently participate in the Magellan network: The first step is to complete the Practitioner Participation Form.
  • If you currently participate in the Magellan network but have NOT signed an AmeriHealth New Jersey Professional Provider Agreement: To obtain a contract, you must submit an application through credentialing. This enables us to verify your credentials with Magellan and then issue you a contract.
  • If you currently participate in the Magellan network and have signed an AmeriHealth New Jersey Professional Provider Agreement: You do NOT need to do anything. Your current credentials will remain in effect on January 1, 2023. If you are scheduled to be re-credentialed in 2023, Magellan (on behalf of AmeriHealth New Jersey) will perform recredentialing and pass the results to AmeriHealth New Jersey. Please be sure to respond to all recredentialing requests to ensure continuous participation. If you are a participating practice, please make sure that your practitioner roster is up to date.

Behavioral health practitioners joining existing contracted groups

  • If you have a new practitioner joining a Contracted Group contracted with Magellan, or contracted with both Magellan and AmeriHealth New Jersey, please submit all credentialing material to Magellan.
  • If you have a new practitioner joining an AmeriHealth New Jersey contracted group that does not contract with Magellan, initiate the credentialing process at AmeriHealth New Jersey by completing the Practitioner Participation Form.

Note: While AmeriHealth New Jersey transitions to a directly contracted behavioral health network, behavioral health providers contracted with Magellan will continue to be considered in network through 2023. If you have any questions related to your Magellan agreement, you can contact Magellan Provider Services Line at 1-800-788-4005 for assistance.

Magellan Healthcare, Inc., an independent company, manages mental health and substance abuse benefits for most AmeriHealth New Jersey members.

Reimbursement terms effective January 1, 2023:

  • If you currently participate in the Magellan network but have not signed an AmeriHealth New Jersey Professional Provider Agreement, you will be considered as participating in the AmeriHealth New Jersey network and will be reimbursed in accordance with the terms and conditions specified in the Magellan Professional Provider Agreement.

    While you will maintain your in-network participation status to provide services to AmeriHealth New Jersey members, you will not be eligible for the AmeriHealth New Jersey terms and conditions (including provider appeal rights and the enhanced AmeriHealth New Jersey reimbursement) until you sign an AmeriHealth New Jersey Professional Agreement.

Please refer to the steps above to complete the contracting/credentialing process.
